The neighborhood concept is already in place in several areas.

For example:

Joe Patriot lives in a mostly self sufficient rural community. Over the years he has learned just who his neighbors really are. He has been networking with them for several years...working on emergency preparedness and self sufficiency...setting up an off the grid communications system and engaging in some hard core target practice. All of these folks live within close proximity of each other.

This small group of neighbors watch each others back. They even have a unofficial neighborhood watch set up in the area.

Everyone has agreed upon certain commitments to each other or the group as a whole.

Over time they've reached out to others within the neighborhood and to some from other areas. As land or housing comes up for sale, the neighborhood notifies these outsiders and more trickle into the area.

The process continually expands...
